AUH Telescoping Stabilizer Jacks for Trailers — 1,200 lb Pair, Adjustable 12–18" Height and Foldable Zinc-Coated Steel

AUH telescoping stabilizer jacks are foldable, adjustable supports that reduce slide-rail sag and steady utility trailers with up to a 1,200 lb combined capacity.

These upgraded trailer jacks attach beneath the slide rail to prevent bending and movement when your trailer is parked or loaded. Built from heavy-gauge steel with a zinc powder-coat finish, the pair resists corrosion and stands up to outdoor conditions while allowing quick height adjustment and compact folding for travel.

How do these stabilizer jacks prevent slide-rail sag?

When extended under the slide rail, the telescoping design creates a solid vertical support point that relieves stress on the frame. That added support keeps the rail level and reduces flexing during loading or when gear shifts inside the trailer.

• Telescopes in and out for precise rail contact.
• Wide base spreads loads to avoid concentrated pressure.
• Plain flat tops fit most slide-rail profiles without modification.

What materials and finish protect the jacks outdoors?

AUH uses heavy-duty steel for structural strength, and the parts are finished in a zinc powder-coat to slow rust and resist chipping. That combination delivers durability for seasonal exposure and repeated mounting and removal.

• Thick steel tubing for load-bearing stability.
• Zinc powder-coat surface for corrosion resistance.
• Hardware included with protective coatings to match the jacks.

How adjustable are the jacks and what load can they carry?

Each jack extends between 12" and 18", so you can dial in support for a range of trailer clearances and ramp positions. Individual jack capacity is up to 1,000 lbs, with recommended combined capacity—when installed as a matched pair—covering typical utility trailer stabilization needs up to 1,200 lbs depending on mounting configuration.

• 12" to 18" adjustable height range for common trailer setups.
• Flat top fits most slide-out frames and utility rails.
• User-friendly spread and rotate action for secure placement.

How simple is installation and what comes in the kit?

The jacks come with the bolts and fasteners required for direct bolt-on mounting so you can attach them to your trailer without fabricating brackets. Both top and bottom pivot so you can stow them folded against the frame during transit and deploy them quickly when parked.

• Complete hardware kit included for straightforward installation.
• Bolt-on design fits most utility trailer frames and slide rails.
• Foldable joints swivel for compact travel position and full spread under load.

Who this is for: These AUH telescoping stabilizer jacks suit owners of utility trailers, slide-outs, small campers, and work trailers who need a durable, low-profile way to stop sagging and add lateral stability while parked. They’re for users who want a bolt-on, corrosion-resistant solution with simple height adjustment and a compact folded footprint for safe towing.
